Handcrafted Redwood Cold Plunge with 1/4 HP Chiller & Ozone

Description

Handcrafted in San Diego from selected redwood, this cold plunge combines traditional woodworking techniques with an integrated cooling and water-treatment system. Each tub is finished using the Japanese Shou Sugi Ban charring technique, which creates a distinctive darkened surface while highlighting the natural grain of the wood.

The plunge arrives fully set up and operates from a standard 110V outlet. A 1/4 HP chiller, 950 GPH pump, filtration system, and ozone water-treatment system are integrated into the setup, providing a complete cold-plunge configuration designed for straightforward maintenance.

Key Benefits

  • Handcrafted redwood construction — Each tub is individually crafted with selected redwood for a distinctive natural appearance.
  • Shou Sugi Ban finish — Traditional Japanese charring creates a textured finish that emphasizes the wood grain.
  • Integrated cooling system — The included 1/4 HP chiller and 950 GPH pump provide water circulation and temperature control.
  • Ozone water treatment — An integrated ozonator provides ozone-based water treatment without relying solely on conventional chemical treatment.
  • Standard 110V operation — Connects to a regular 110V household outlet, with GFCI or grounded outlets recommended as required by applicable laws.
  • Adjustable water depth — The approximately 60-gallon capacity allows water height to vary based on body displacement and preferred immersion level.
  • Preassembled setup — The tub arrives fully set up, reducing installation requirements.
  • Straightforward maintenance — Filter replacement is typically required every 1–2 months, depending on usage.
